A few possibilities but check the plug in something else first. Does it work.

Take out the power supply and plug the working plug into it. Does it's fan spin ? If it does, possible the power supply is ok.

Check it out like that. Put the power supply back in and keep adding a part and see if the next in sequence comes to life. Sometimes one part may be faulty and pulling down the voltage. It is a matter of elimination.

The power supply fan isn't spinning when new motherboard is installed but it does spin when the old motherboard is in its very strange

That would point to something on the new motherboard then.

Have a look at this, maybe it might point you in the right direction

have you double checked your cables on motherboard, ensuring everything is clicked into place using the correct cables?

the power switch cable in particular is a tiny cable that you might have put in the wrong slot or wrong way around?

the PSU might not spin anyway until enough load is being pushed through it, a lot of PSU's these days are silent(no fan spinning) until at a certain draw level

The corner of the motherboard is touching the case I think it's the motherboard that's shorted

Did you not use stand off's?

Yes I did but the motherboard is a big too big so one bottom corner was touching case

You are not getting around this without a bigger case or at a push, taller standoffs.

Ok so I just put all the old parts in again and 2 LEDs come on as usual and I do have everything placed in correctly but it won't start same as the new motherboard could this be a the button? I was told the new motherboard doesn't have those little LEDs so maybe it's not the new motherboards fault?

you need to rule out things,

can you assemble it outside of the case to rule out that its shorting inside your case, the motherboard must have a pinout for the power button, it needs to be in the correct one at right orientation

I have assembled outside case still does the same thing power sw is in the right place
